Set top box for pioneer

[samboss]

I have a Pioneer HD plasma 43", i also purchased a Pioneer HD set top box. The picture is OK, but I would like to know if anyone can reccomend the best box out there. i have been pointed towards the Topfield, Sony or Toshiba by a few mates. All a little confusing at the moment.

Plasma is 1024 x 768 component in

Thanks
